TPS65133
- 2.9-V to 5.0-V Input Voltage Range
- Fixed 5.0-V Positive Output Voltage (VPOS)
- Fixed –5.0-V Negative Output Voltage
(VNEG) - ±1% Output Voltage Accuracy
- High Efficiency
- 250-mA Output Current Capability
- Independent Converter Operation Allows 100%
Output Current Mismatch - Excellent Line and Load Transient Response
- Operates in CCM to Minimize Output Noise
- Boost Converter able to Operate with Input Supply
Voltages close to 5.0 V - Short-Circuit Protection
- Thermal Shutdown
The TPS65133 is designed to supply any system requiring ±5.0-V supply rails. Each output can supply up to 250 mA of output current. The input supply voltage range is suitable for use with lithium ion batteries or from a fixed 3.3-V supply.
Efficiency is typically over 90% for most applications (operating from a lithium ion battery, output currents in the range 50 mA to 200 mA). The two converters in the TPS65133 device operate independently, allowing 100% mismatch between positive and negative output currents.
